To all whoml it may concern:

Be it known that'I, DUANE H. CHURCH, o Waltham, in the county of Middlesex, State ,of Massachusetts, did invent certain new andl 5 useful Improvements in Stem Winding and Setting Watches, for'which Letters Pat-ent of the United States were -issued upon the 18th day of March, 188,4, which Letters Patent have been found to be defective and invalid, ro and not to cover the inventionset forth in the 'specification and shown in thedrawings, which were filed in the Patent Oice upon the 23d day of August, 1883, preparatory to the obtaining of the said Letters Patent. Now, x5 therefore, being desirous of reissuing thesaid Letters Patent,I have prepared and do hereby declare the following to be a full, clear, and exact description of the said improvements, referencev being had to the accompany- 2o ing drawings, in which- F' ure l is a plan view of a portion of a4 watc containing my improvements, the dial being removed and the steni-d'riven mecha nism in position for setting the hands. Fig. 2

25 is a like .viewof' the same with said stemdriven mechanism in position for winding the spring. Figs. 3 and 4 are plan views of op osite sides-of said watch, and show the windmg and hands'setting mechanism. arranged to be manipulated entirely by the stem-arbor;

and Figs. 5 and 6 are sections upon lines :c :v and z z, respectively, of Figs. 1 andv 2,

*Letters of like name and kind refer m like.

pnrts'in each of the figures. 1 This invention relates to astem windingand setting watch in which connection is made between the stemdriven train .and the dialwheels by means of an intermediate wheel that is shifted into or out of engagement therewith in a direction perpendicular to its plane of rotation; and the object of said invention is to cause such operation to be performed by or inconsequence of the movements of the pivotedyoke as it moves said train into or out'of engagement with the winding-wheel.

To this end my said invention consists, principally, as an improvement in stem winding and setting watches, in combining with the -stem winding and setting watches, in a stemdial-Wheels and with a stemdriven train which is provided with a pivoted yoke, an intermediate wheel which is adapted to connect or to` disconnect said dial-wheels and train, and by the movement of said yoke is shifted in a line perpendicular to its plane .of rotation, substantially as and for the purpose hereinafter specified.

It consists, further, as any improvement in stem winding and setting watches, ill-combining with the dial-wheels and with astem-driven train which is provided with a pivoted yoke an intermediate Wheel that is shiftable in a line perpendicular toits plane of rotation, and by the movement of Said yoke is permitted to engage with or is disengaged from sa-id' diall-I wheels and trai-n, substantially as and for the. purpose hereinafter Shown.

It consists, further, as an improvement in stem winding andv setting Watches, in combining with the dial-wheels and with a stemdriveu train, which is provided with a piv-Y oted yoke, an intermediate wheel that by the action of a spring is shifted in a line perpendicular to its planejof rotation into engage# ment with said dial-wheels and train, and 'by the motionl of said yoke is shifted inthe samev line out of engagement with said parts, .substantiallyas and for the purpose hereinafter set forth.

It consists, finally, as anr improvement in driven train which is in part journa-led. upon a pivoted yoke, andan intermediate wheel that by the movements of said yoke and the action of a spring is shftable in aline perpendicular to its plane of rotation, said parts being combined and arranged to operate in the order shown, wherebyas said train Ais engaged with the spring-wheel itis automatically disengaged from the .dial-wheels. and when engaged with said dial-wheels it is by the same operation disengaged from said winding-wheel, Substantially as and for the purpose hereinafter shown and described.

In the annexed drawings, A represents a portion of the center band of a watch-case having a pendant, a, and l) the upper plate l j f- 10,530- n of Aa-watch-inovement,which plateis fittedio lof the plate B, -and has its toothedl periphery and secured within said in the usual man@i Jonrnaled .within the pendant a is a sitemarbor, C,v which at its inner end enters into and engages with a pinion, 'D,' that is journaled in a suitable bearing upon the'lo'wer face extendingl through anfopening, b, `whichis provided in said plate, where it meshes with 'a Vtoothed wheel', E, that is journale'dnpon the llatterby means ofa screw, F, the arrangement being such as to enable sai'd wheel E to be 'rotated in either direction by the rotation of stemarbor. y.

Upon the upper end of the screw F is pivoted a yoke, G, which has the usual form in.

plan view. and has pivoted upon its lower face at one end a toothed wheel, H, that meshes vwith the wheel E, and bythemovement of said :yoke upon its pivotal bearing may be moved into or out of engagement with a wheel,

I, thatv is 'attached to the mainspring-arbor, all in -the usual manner, and for the purpose of enabling the mainsprin'g to be wound by the rotation of the' stem-arbor C.

' The watch-movement is providedy with the usual diallwheels, Kyand between one of the same and the wheel E is placed an intermedi-` 3o ate lwheel, L,`that has such diameter as to enable it to meshwith and connect said wheels.

' Said -wheelL is journaled upon a stud, b', that projects upward from the plate B, and around said stud is formed a recess, b?,- which has such diameter and depth as to enable saidwheel .L tobe moved downward in a line perpendicular to its plane'of rotation a distance sufficient to disengage it from the dial-wheel K. Said wheel vEhas preferably such depth as to cause said intermediate wheel t0 remain in engagement ltherewith vwhether in or out .of engagement with saiddial-wheel.

The'iptermediate wheel, L, is .held with a yielding pressure at the upper limit of its motion in engagement with the dial-wheel K by means of a spring, M, placed beneath, and is moved to the lower limit of itsmoton out of engagement with said dial-wheel by the movement of the yoke G upon its pivotal bearing, such last named operation being effected asv follows, viz: The stud Za has such length asto permit the yoke G to swing freely over its upper end, while the intermediate wheel, L, has 4its upper side, l, constructed in the form of a cone, the apex of which bears against the lower face oi' said .yoke and is held in engagement therewith by the spring M, in which position said yoke loperates to hold said wheel at the lower limit of its motion out of engagement with the dial-wheel. l

Within the yokeG is formed a recess, g, which, when said part is turned to the posi,

. tion shown in Figsf 1 and 5, so as to disengage the stem-driven train from the windingwheel I, comes 'directly` over the axis ofthe intermediate wheel, L, and permits the latter to be raised by the spring M into the plane of Vuit dial-wheel Yi; Vwith its mmcaiuppl-.r ad,

l, projecting upward into said recess, while' whe'nsaid yoke is moved -in an opposite rection, seas to cause said train -to'engage'with 4said Winding-wheel, the side'. of said' recess .moves over theinclined face of said conical part l'and'forces'said wheel' L downward ont of engagement -with said dial-'wlieeL such movements-of said intermediate wheel auto matically resulti ng from the oscillations of said. yoke.

Thel yoke tionto another by means of the longitudinal movement of the stein-arbor C, in which event a spring, N, is secured to the lower face of the plate B and caused to engage with a stud, g', which extends from the winding-wheel end of said yoke downward through an opening in G-.may be shifted from one4 posisaid plate, the arrangement'of said spring being such as to cause it to hold said yoke in p osition to enable the hands of the watch to be set, except when, by an inward movement of said stem-arbor; communicated to thel outer side of said spring N, the outward pressure of [the latter is neutralized and it is moved in the same direction sufficiently to changeA the' position of said yoke and cause the stem-'driven train to engage withsaid winding-wheel I.

Upon drawing said stem-arbor outward again,

said spring N is permitted to act and immediately restores said yoke to its former posif -tion with the said train in engagement with'.

the dial-wheel.

When the stem-arbor is not longitudinally IOO movable, the yoke G may be turned-to posi# ftin to cause the stem-driven train to engage with the winding-wheel I by meansl of a Z- shapedlever, O, which, asshown in Figs. 1 and 2, is pivoted upon the plate B in position to enable the end of one of its arms, o,l to 4en gage with the end of said yoke adjacent to the intermediate wheel, L, and move the same inward whenever. the opposite arm, o', of said lever is drawn outward from beneath the bezel of the case, as seen in Fig. 1. When said lever is disengaged from said yoke, as shown in Fig. 2,- a spring, P, bearing against theoppositewinding end of the latter, moves it to and holds it in position to cause engagement ofthe. train-wheel H with the winding-wheel I..

Having thus described my invention, what I claim is- 1. As an improvement in 'stem Windingand `setting watches, inv combination with`the dialwheels, and with a stem-driven train whichl is provided .with a pivoted yoke, an intermediate wheel which is adapted toy connect orto disconnect said dial-wheels and train, and by kI Io the movement of said yoke is shifted in a line lperpendicular toits plane of rotation, vsubstantially as and for the purpose specified.

2. As animprovement in 'stem winding and setting watches, in combination with the dial-- wheels, and with a stem-driven train which is provided witha pivoted yoke, an intermediate wheel that is shiftable in a line perpendicular to its plane of rotation, and bythe movement ol said yoke is permitted to engege with or is disengaged from said dialwhecls und iriin, substantially as und for the purpose shown.
